SPECIFICATION forming part of Letters Patent NO. 587,336, dated August 3, 1897.

Application filed April 9, 1896.

T0 all whom, it may concern:

Be it known that I, FRANc MonRIsoN SHORT, a citizen of the United States, residing atCleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in a System of Telegraphy, of which the following is a specification.

This invention relates to a system of telegraphy.

The object of the invention is to provide a system of telegraphy of simple and improved construction and arrangement of parts whereby any desired message or design may be reproduced at the receiving end of the line.

The invention consists, substantially, in the combination, construction, location, relative arrangement, and operation of parts, all as will be Inore fully hereinafter set forth, as shown in the accolnpanying drawings, and finally pointed out in the appended claims.

Referring to the accompanying drawings and to the various views and reference-signs appearing thereon, Figure 1 is a view illustratin g an arrangement of apparatus embodying the principles of my invention. Fig. 2 is a view illustrating an arrangement of apparatus in accordance with the principles of myinvention as adapted to the transmission of the ordinary Morse alphabet. Fig. 3 is a view illustrating an arrangement of apparatus in accordance with the principles of my invention wherein an ordinary Morse transmitter may be employed as the sending instrument. Fig. 4 is a view illustrating an arrangement of apparatus in aocordance with the principles of my invention wherein a vibrator is employed at the sending end of the line. Fig. 5 is a view illustrating an arrangeinent of apparatus in accordance with the principles of my invention and showing an arrangement for synchronizing the movements of the sending and receiving apparatus. Fig. 6 is an enlarged detail view, partly in section, illustrating a form of recording apparatus at the receiving end of the line embodying in its construction, arrangement, and principle of operation the prineiples of my invention.

The same part is designated by the same reference-sign wherever it occurs throughout the several views.

In carrying out my invention I provide at the sending end of the line a piece or block Serial No. 586,890. (No model.)

A, of suitable insulating material, through which 'and parallel to each other I pass the wires or conductors a b, having their projecting ends o d. on either side of said insulating material arranged in close proxiinity to each other and preferably, though not necessarily,

pointed toward each other after the manner' of a double-pointed pen, said ends, however, being out of contact with each other. The other end of the wire or eonductor a is in cireuit through a suitable connection or conductor e and battery or other form of generator B to ground, as at f. The other end of wire or conductor Z) is included in circuit with a suitable connection or conductor g, which may constitute the line-Wire over which the message or design is transmitted, and which line-Wire is arranged at the receiVing-station to be included in circuit with the coils of an electromagnet O, and thence to the ground, as at h. To the armature of the electromagnet is suitably connected the style D of a fountain-pen F or other suitable arrangement of fountain or receptacle containing ink or other writing or recording material, whereby when the said style is reciprocated or projected endwise by the movement of the armature of the electromagnet it carries upon or in advance of the point thereof a tiny drop of ink, while at the same time it closes up the orifiee in the fountain F while so projected and prevents the iiow of ink therethrough from the fountain, the next movement of the style in the opposite direction again permitting a tiny drop of ink or other writing or recording material to fiow out of the fountain or receptaole F in advance of the style to be again deposited upon the receiving-blank upon the next succeeding projection of the style.

If desired, and preferable, I impart to the style D arapid reciprocation during the operation of the apparatus, and to .this end l attach said style D to an arm or spring E, which carries or forms part of the armature of the electromagnet O, and which is included electrically in circuit with the coils of the electromagnet O in a well-known manner, whereby When said arm or reed E moves or vibrates in one direction it contacts with a point G, included in ci'rcuit with the line-Wire g, thereby energizing the coils of the electromagn et when IOS current is flowing through said line-wire and causing the armature to be attracted, thus projecting the style D, but at the same time breaking the eircnit of the electromagnet, thus removing` the attracting force and permitting the reed to again vibrate in the opposite direction to again make contact with point G, and so on, as long as current is fiowing through the line-wire.

From the above description it will be seen that when circuit is made between the ends or points c (Z a current will flow through line wire or conductor g and the armature of the electromagnet O will be attracted, thereby projecting style D and causing a tiny drop of ink to be deposited upon the receiving-blank, or, in case the vibrator arrangement is employed, as above explained, a number of tiny drops of ink are deposited upon the receiving-blank. The message or design to be transmitted is first produced upon any suitable material, as m, in any suitable way, preferably a metallic or electrically-conducting ink, adapted when the points c (Z are brought in contact therewith to close the circuit therebetween. Now snppose the receiving-bla-nk n and the transmitting or message blanl: m are suitably connected by a synchronizing apparatns,whereby they are moved in unison, or su ppose the transmitting or sending points c (Z are connected through suitable synchronizing` apparatns with the fountain F, so that the movements of the one are transmitted to and reproduced in the other, then it will be seen that as often as the points c (Z are brought into contact with the inl; or other material forming the design or message on the sendingblank m eircuit is closed therethrough and the style is operated to reproduce the same at the receiving end.

In Fig. 1 I have shown as merelya conventional arrangement illustrative of the principle involved the transmitting-points c (Z, connected to the fountain F through a rigid rod II. Therefore as the points c (Z are moved over the message or design on the sending-blank m, prepared as above explained, and as said points come in contact with the various portions of the letter 01' design to be transmitted the same movements are transmitted to the fountain F, while at the same time the style G is projeeted, or, in case a vibrator is used, is given a rapid reciprocation, thereby reprodncing by a series of dots the Outline of the letters forming the message or of the design. By suitably regulating the rapidity of the reciprocation of the style D the series of dots made therehy on the receiving-blanl; will form practically a continuous line, thereby reprodncing the message or design at the receiving-station.

In Fig. 5 I have shown a different embodiment of the idea of synchronizing the apparatus at the receiving and sending stations, wherein the sending-points c (Z and the fountain F are synchronously moved by means of suitable synehronizing motors L L. It is evident, howevcr, that the said motors may be arranged to synchronously move the sen ding and receiving blanlcs instead of the sending and reeeiving instruments.

In Fig. 2 I have shown an arrangement wherein the ordinary Morse al phabet is transmittcd and reprodnced, the sending-blank m containing the message previouslyprinted or written thereon in metallic ink, as above explained, the Morse alphabet being employed, and the reciprocations of the style D at the opposite end of the line accurately reprodncing the same upon the receivingblank n, it being understood that the receiving-blank 72v is meanwhile fed or reeled off synehronously with the feed of the sendingblanl; m, as above explained.

In Fig. 3 I have shown the sending instrument in the form of an ordinary Morse instrument K. In this case it will be readily seen that the Morse characters will be accurately reproduced and recorded at the receiving-station upon a suitably-fed receivingblank n.

If desired, the vihrator O E may be arranged at the transmitting end of the line, as indicated in Fig. i, and which willoperatc to send an intermittent current over the line. It will be seen that this arrangement may be employed to secure synehronous action of the apparatus at the sending and receiving ends of the line.

From the foregoing description it will be readily seen and understood with my system IOO of telegraphy, as above explained, that the services of an expert sender or receiver are not required, but that any one hovvever unskilled may send or receive a message. It will also be seen that the systemis thoroughly practical for transmitting the Morse alphabet or facsimile telegrams or the transmission and reproduction of any design which may be drawn or written on the sending-blanlc. The number of words per space of time which maybe transmitted in accordanee with the prineiples of my invention is unlimited. Several sending or receivingstations may be operated over the same lineby using the sender and receiver in connection with the ordinary multiple synchronizers in the same manner that the ordinary Morse instruments are at present used. It will also be seen that as the style moves orreciprocates very rapidly when a vibrator is used, making several hundred reciprocations or vibrations per second, and by suitably regulating the relative speed of movement of the fountain and receiving blank the dots overlap each other and form praetically a continuous line during the flow of current over the line-Wire. By suitably regulating the amount of inl; or reeording material deposited with each reciprocation 01' vibration of the style or by employing a suitable absorbent material for the receivingblank the inlc or other material employed is prevented from drawing along the receivin g material during the relative movements of IIO the receiving instrument and the receivingblank, thereby reproducing the message or design in clear, sharply-defined lines.

I'Iaving now set forth the objects and nature of my invention and Various illustrative forms and arrangements of apparatus embodying the same and having explained the function, construction, and mode of operation thereof, I desire it to be distinctly understood that I do not limit or restrict myself to the particular form or arrangement of apparatus disclosed, as the principles of my invention may be embodied in a Wide variety of specifically different forms and arrangements of apparatus and still fall Within the spirit and scope of my invention; but
